BURGLAR emv.

To all whom t may concern: 4

Be it known that I, FRANCIS 55.* JonsoN. a citizen ot the United States7residing at Mentone, in the county of Dekalb and State ct Alabama, haveinvented certain new and useful improvements in Burglar Guns. ot' whichthe Y'tfolloning is va iull7 clear, and exact dcscription. f Y

My invention relates to a burglar gun and has for its object to providesuch a device which is simple in construction and opera.- tion andtherefore of low cost in manufacture. f Y

Another object ot' the invention vis to provide a burglar gun or alarmwhich may be set in such manner as to merely give an alarm or to Woundor kill anintruder.

A 'further object of the invention provide such a device with a safetywhereby the same may be locked so avoid a premature explosion While(lling, etc.

@ther objects and advantages ot the invention will be apparent from thefollowing description when taken in connection with the accompanyingdrawing in which,

Figure 1 is a side elevation ot the device.

Figure 2 is a plan View thereof.

Figure 3 is a4 fragmentary vertical section through the gun showing theoperation ot the firing pin.

Figure .4f is a rear view partly in section` clearly showing the safetycatch, and./

Figure 5 is a 'fragmentary section throu a modified form of the device.

Referring to the drawing more in detaih the numeral 1 designates a basemember provided with screw holes 2. whereby the apparatus may besecurely bolted to a counter, desk, or the like. Extending vertically'from the base 1 are a plurality of standards'or iframe members 3. l andThe member is bored horizontally to provide :i socket- (3 tor thereception orn a gun barrel 7rr `which latter is firmly held in place bya set-screw 8.

Formed in the opposite end oi? the standard 3 a cylindrical passage 9 inwhich is mounted the tiring pin 10 normally held in retracted positionby the spring ll. A

to latch to hanscreW cap 12 is provided for locking the pin 1 0 andspring 11 in the cylindrical passage.

Mounted tor longitudinal movement in the standards and 5 is a normallypressed toward means ct' the coll spring plunger or rod 13 the tiringpin by 111-.7 Which abuts the Specification of Lettersatent.

standard at one end the pin 15 at the opposite end. The rod i?) isprovided with a linger grip 16 'tor withdrawing the same against thepressure of the spring- 14.

ln order to hold the plunger in retracted position the same is providedwith an annular groove 17 which receives'an edge or' the lover 187 thelatter-being pivoted at 19 to the rear ot' the standard 5. bell-cranklever 2O is pivoted to ythe side ot the stand-- ard 5 and has itsshorter -arm Q1 in engape ment with the free end of the lever 1S. Itwill thus be `seen that when the bell-crank lever 21 is rocked on itspivot in the proper direction the lever 18 Will be released from thegroove 17 and permit the plunger 13 to move to the right 1). For thepurpose of moving the bell-crank 20 on its pivot l provide an armv Q52pivoted to the'top ot the standard 5 at 23. This arm 22 engages thelonger arm of the bell-crank 2O and has a cord or lanyard 24 secured toits free end. The opposite end of the lanyard is tree to be secured toany part of the room. office, or the like best suited for the purpose.The tell-crank 20 is also provided With an aperture 25 at its upper endfor the direct connection of the lanyard 24 thereto when 'founddesirable. A latch 26 is pivoted to the rear of the standard and isadapted to engage the lever 18 and hold the same in the groove 17 toprevent accidental firing of the gun during'handling.

ln Figure 5 I have shown a slightly modi fied Jform of the inventionwherein the iring pin 10 and plunger 13 are Jformed integrally. ln otherrespects this form of the invention is identical with that previouslydescribed.

ln operation, the base 1 is secured in the most advantageous position ina bank or the like. The barrel 7 is removed .T'rom the standard 3,loaded. and replaced. The plun- `ger 1S or 13, as the case may be, isdrawn against the pressure of the spring 14 until the groove 17 is underthe lever 18; the latter then drops by gravity into the groove andthereby locks the plunger in retracted position. The free end ot thelanyard 24 is then taken to a suitable place in the room and securedWith the lanyard reasonably taut. It it is intended to kill or seriouslyWound the trespasser the lanyard is pla-ced in line with the barrel ofthe gunj While if it is intended to slightly Wound or merely frighten.oil' the intruder the lanyard may 'ne placed at an angle to the barrelof the gun. In moving or otherwise Working with the gun in loadedcondition the latch 26 is swung into the position shown in Figure 4.

It will be seen from the foregoing that I have provided a simplifiedform of burglar gun which may be easily and quickly p-ut in place, andfurthermore one which is adjustable to either frighten, Wound or kill anin truder.

In accordance with the patent statutes I have described what I nowbelieve to be the best embodiment ot' the invention, but I do not Wishto be understood thereby as limiting myself or the scope of theinvention, as many changes and modiiications may be made Withoutdeparting -from the spirit of the invention, all such I aim to includein the scope of the appended claims.

'Vhat I claim as new and desire to secure by Letters Patent is:

1. A burglar gun including a base, a plurality ot' standards extendingupwardly therefrom, a barrel and afiring p in mounted in one of saidstandards, a spring-pressed plunger mounted on another of said standardsand operatively connected with the firing pin, said plunger having anotch formed therein, a lever normally engaging said notch, and a bellcrank lever normally in Contact with said first-mentioned lever andadapted to lift the same from the notch in said plunger.

2. A burglar gun including a base, a barrel and a firing pin mounted onsaid base, a standard, a spring-pressed plunger mounted thereon andoperatively connected with the firing pin, said plunger having a. notchformed therein, a lever pivoted to the rear of said standard andnormally engaging said notch, and a bell-crank lever pivoted at one sideof the standard and normally engaging the first-mentioned lever.

3. A urglar gun including a base, a barrel and a firing pin mounted onsaid base, a standard, a spring-presser plunger mounted thereon andoperatively connected with the firing pin, said plunger having a notchformed therein, a lever pivoted to the rear of said standard andnormally engaging said notch, a` bell-crank lever pivoted at one sideOt' the standard and normally en gaging the ,first-named lever, and alatch 'For locking said tirst-named lever in its plunger engagingosition.
